Persistence test

This should be run on an unfished, unperturbed run. Fishing or perturbations may legitimately drive groups extinct.

Stability test

Model reaches steady state for last ~20 years of an unperturbed, unfished ~100 year run.

# assumes biom.txt output already read in

# look for non-significant linear slope over last 20 years? 30 years would be better

Establish hindcast period

See discussion here and here.

The period is defined as 1980-2010 for trend comparison. Change it here to see different results:

hindcast <- c(1980:2010)

Data sources include ecodata and stock assessment outputs for major species.

Interim step: which species to include and what data are in the reference set for comparison

Not all species need to match, we will first determine the most important subset(s). Based on discussion, we want to track the species the comprise 80% of biomass (and 80% of catch and 80% of revenue).

Code to evaluate which species are most important based on biomass, catch, and revenue, union and intersection.

# first past B, catch, revenue, use ecodata

survbio <- ecodata::nefsc_survey_disaggregated %>%
  filter(Time %in% hindcast) %>%
  group_by(comname) %>%
  summarize(avgkgtow = mean(kg.per.tow, na.rm = T)) %>%
  mutate(prop = avgkgtow/sum(avgkgtow, na.rm = T)) %>%
  arrange(desc(prop))

hibiosp <- stringr::str_to_sentence(survbio$comname[cumsum(survbio$prop)<0.81 & !is.na(cumsum(survbio$prop))])

# comdat and bennet are already aggregated in ecodata

# need comland, should be able to run similar code as above to get catch and revenue

# time series in case we want to plot them
comlandts <- merge(comland, spcodes) %>%

Code to develop the hindcast comparison (call it “reference”) dataset:

# simplest is annual output comparison, but which season should be compared to Atlantis? 

# WARNING our names dont match between survbio comnames and comland Name, fix above

survbio.ts <- ecodata::nefsc_survey_disaggregated %>%
  filter(Time %in% hindcast) %>%
  mutate(comname = stringr::str_to_sentence(comname)) %>%
  filter(comname %in% hibiocatvalsp) %>%
  group_by(Time, Season, comname) %>%
  summarise(annkgtow = sum(kg.per.tow))

tsplot <- ggplot(survbio.ts, aes(Time, annkgtow, color=Season)) + geom_point() + ggthemes::theme_tufte() + facet_wrap(~comname, scales = "free")

grid.draw(shift_legend(tsplot))

## Warning: Removed 512 rows containing missing values (geom_point).

# ecosystem indicators for comparison: total survey biomass
survbio.tot <- ecodata::nefsc_survey_disaggregated %>%
  filter(Time %in% hindcast) %>%
  group_by(Time, Season) %>%
  summarise(annkgtow = sum(kg.per.tow, na.rm = TRUE))

ggplot(survbio.tot, aes(Time, annkgtow)) + geom_point() + ggthemes::theme_tufte() + facet_wrap(~Season)

Species qualitatively match trends

Key species to match and their most representative trend datasets are determined in analyses above, and the code that looks for the match between this reference set and Atlantis output is developed here. By match we mean significance and direction only.
